SHAPING CIRCUITA circuit that alters the shapes of input waveforms [9]. | |
SHARP-CUTOFF TUBEThe opposite of a remote-cutoff tube. An electron tube that has evenly spaced grid wires. The amplification of the sharp-cutoff tube is limited by the bias voltage and tube characteristics [6]. | |
SHELF LIFEThe period of time that a cell or battery may be stored and still be useful [1]. | |
SHIELDED PAIRA line consisting of parallel conductors separated from each other and surrounded by a solid dielectric [10]. | |
SHIELDING(1) A metallic covering used to prevent magnetic or electromagnetic fields from affecting an object [1]. (2) Technique designed to minimize internal and external interference [14]. | |
SHORT CIRCUITAn unintentional current path between two components in a circuit or between a component and ground; usually caused by a circuit malfunction [1] [3] [16]. | |
SHORT-CIRCUITED LINEA transmission line that has a terminating impedance equal to 0 [10]. | |
SHUNTA resistive device placed in parallel with another component. Appreciable current may flow through it and an appreciable voltage may exist across it [12]. | |
SHUNT PEAKINGA technique used to improve high-frequency response in which a peaking coil is placed in parallel (shunt) with the output signal path [8]. | |
SHUNT RESISTORA resistor in parallel. In an ammeter, shunt resistors are used to provide multiple ranges [3]. | |
